Title (EN) LYOTROPIC LIQUID CRYSTALLINE L3 PHASE SILICATED NANOPOROUS MONOLITHIC COMPOSITES AND THEIR PRODUCTION
(FR) COMPOSITES MONOLITHIQUES NANOPOREUX, SILICATES, A PHASE L3 CRISTALLINE, LIQUIDE, LYOTROPIQUE ET LEUR PRODUCTION
Abstract:
(EN) A mesoporous ceramic material is provided having a pore size diameter in the range of about 10-100 nanometers produced by templating with a ceramic precursor a lyotropic liquid crystalline L3 phase consisting of a three-dimensional, random, nonperiodic network packing of a multiple connected continuous membrane. A preferred process for producing the mesoporous ceramic material includes producing a template of a lyotropic liquid crystalline L3 phase by mixing a surfactant, a co-surfactant and hydrochloric acid, coating the template with an inorganic ceramic precursor by adding to the L3 phase tetramethoxysilane (TMOS) or tetraethoxysilane (TEOS) and then converting the coated template to a ceramic by removing any remaining liquids.
(FR) Cette invention se rapporte à un matériau céramique mésoporeux possédant un diamètre de pore compris approximativement entre 10 et 100 nanomètres, que l'on produit en formant, à l'aide d'un précurseur de céramique, une matrice de phase L3 cristalline, liquide, lyotropique, consistant en un entassement de type réseau tridimensionnel, aléatoire et non périodique d'une membrane continue à connexion multiple. L'invention se rapporte à un procédé préféré de production d'un matériau céramique mésoporeux qui consiste à former une matrice de phase L3 cristalline, liquide, lyotropique en mélangeant un tensioactif, un cotensioactif et de l'acide chlorhydrique, à recouvrir la matrice avec un précurseur de céramique inorganique en ajoutant à la phase L3 du tétraéthoxysilane (TEOS) ou du tétraméthoxysilane (TMOS) puis à transformer la matrice recouverte en une céramique en extrayant tout liquide résiduel.
